Subject: [PATCH 1/2] fsi/sbefifo: Clean up correct FIFO when receiving reset request from SBE
Date: Fri, 24 Jul 2020 16:45:17 +0930	[thread overview]
Message-ID: <20200724071518.430515-2-joel@jms.id.au> (raw)
In-Reply-To: <20200724071518.430515-1-joel@jms.id.au>

From: Joachim Fenkes <FENKES@de.ibm.com>

When the SBE requests a reset via the down FIFO, that is also the
FIFO we should go and reset ;)
